What is an orb weaver spider?
Orb-weaver spiders are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields, and forests. The English word orb can mean "circular", hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs.

What is an araneid web?
Araneid webs are constructed in a stereotyped fashion. A framework of nonsticky silk is built up before the spider adds a final spiral of silk covered in sticky droplets. Orb webs are also produced by members of other spider families.
Why do orb weavers have bands?
As orb-weavers age, they tend to have less production of their silk, many adult orb-weavers can then depend on their coloration to attract more of their prey. The band may be a lure for prey, a marker to warn birds away from the web, and a camouflage for the spider when it sits in the web.
Where do araneids mate?
Araneid species either mate at the central hub of the web, where the male slowly traverses the web , trying not to get eaten, and when reaching the hub, mounts the female; or the male constructs a mating thread inside or outside the web to attract the female via vibratory courtship, and if successful, mating occurs on the thread.

Tips for Control
Spiny-backed orb weavers are not dangerous and are beneficial animals. They should not be killed if at all possible. In situations where numerous spiders are present, the webs can be regularly knocked down. Steps should then be taken to determine what conditions are attracting so many insects to a home where such a large number of spiders can feed.
Overview
Description
Generally, orb-weaving spiders are three-clawed builders of flat webs with sticky spiral capture silk. The building of a web is an engineering feat, begun when the spider floats a line on the wind to another surface. The spider secures the line and then drops another line from the center, making a "Y". The rest of the scaffolding follows with many radii of nonsticky silk being constructed before …
Taxonomy
The oldest known true orb-weaver is Mesozygiella dunlopi, from the Lower Cretaceous. Several fossils provide direct evidence that the three major orb-weaving families, namely Araneidae, Tetragnathidae and Uloboridae, had evolved by this time, about 140 million years ago. They probably originated during the Jurassic (200 to 140 million years ago). Based on new molecular evi…
Reproduction
Araneid species either mate at the central hub of the web, where the male slowly traverses the web, trying not to get eaten, and when reaching the hub, mounts the female; or the male constructs a mating thread inside or outside the web to attract the female via vibratory courtship, and if successful, mating occurs on the thread.
In the cannibalistic and polyandrous orb-web spider Argiope bruennichi, the much smaller males ar…
